The _____ command allows you to modify the default prompt to provide other information
Answer: A
Correct answer: prompt
The PROMPT command redefines what DOS displays before each command. Its codes stand for pieces of information - $p for the current path, $g for the greater-than sign, $t for the time - so PROMPT $P$G gives the familiar C:\DOS>.

While working with MS-DOS, which command is used to display the contents of a file and pause the display after each screenful of information?
Answer: A
Correct answer: TYPE filename | MORE
TYPE writes the file to the screen without stopping, so its output is piped into the MORE filter, which pauses at the end of each screenful until a key is pressed. CAT and pg are Unix commands, not DOS ones.

Indicate which is a pre-emptive scheduling algorithm
Answer: A
Correct answer: Round-robin
Round robin is preemptive by definition: a process still running when its time slice expires is interrupted by the timer and moved to the back of the queue. Shortest-job-next and simple priority scheduling let the chosen process run to completion or to a block, so they are not preemptive.

When MS-DOS formats a disk, it automatically creates the main directory on your disk, which is called the _____ directory.
Answer: B
Correct answer: root
Formatting creates one directory on the disk, the root, written as \. Every other directory is created inside it or inside one of its descendants, so the root is the base of the whole tree.

While working with MS-DOS, which command is used to move file from one directory to another?

In an absolute loading scheme, which loader function is accomplished by loader
Answer: D
Correct answer: Loading
In an absolute loading scheme the assembler has already fixed the addresses and resolved the references, so the loader has nothing to allocate, relocate or link - it simply places the program at the addresses named and transfers control. Only the loading function remains.
